Nomos 1 TSDPG

Moving from a Peseux 7001ebauche, Nomos began creating their own in-house movement in the 1990's. By March, 2002, they gave this series a name: "Nomos 1". These movements still retained the 7001 architecture and design but featured many changes and could not use the same replacement parts. For this reason, ETA/Peseux had requested that the company change the name.

The most important difference between the Nomos 1 family and the earlier Peseux was the use of Triovis fine regulation. Additionally, Nomos replaced the plate and balance cock of the Peseux with gold plated pieces decorated with Langeleist perlage at the Nomos facility. This would be the company's primary movement family until the 2005 introduction of the Nomos Alpha.
